General case: In-place heapification (bottom-up bubble down heapification) takes O(N) time (naive in-place heapification, or top-bottom bubble up heapification, takes ϴ(NlogN) time). After heapification, we simply remove from the max-heap. The runtime of heapsort is ϴ(N + (time to remove all items)).

In computer science, heapsort is a comparison-based sorting algorithm. Heapsort can be thought of as an improved selection sort: like selection sort, heapsort divides its input into a sorted and an unsorted region, and it iteratively shrinks the unsorted region by extracting the largest element from it and inserting it into the sorted region. Unlike selection sort, heapsort does not waste time with a linear-time scan of the unsorted region; rather, heap sort maintains the unsorted region in a WebIn the final function of heapsort, we make use of create_heap, which runs once to create a heap and has a runtime of O (n).
